Abstract
A method for performing contactless signal testing includes receiving, with a testing pad of an integrated circuit, a signal within a beam. The method further includes converting, with a number of diodes connected to a positive voltage supply, an electrical current signal created by the electron beam to a voltage signal, wherein the number of diodes includes a diode stack of multiple diodes. The method further includes extracting, with a digital inverter, a test signal from the voltage signal.
